π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π One, Product Definition & Classification: Do You Really Understand βRefrigerant Mixturesβ?
Refrigerant mixtures are essential working fluids in household air conditioning and refrigeration systems. In international trade, they are chemically complex substances containing halogenated hydrocarbons (such as HFCs, HCFCs, or HFOs). Because their chemical structure and application scenarios vary, they fall into different HS Code categories depending on whether they are classified as chemical preparations, organic halogenated compounds, or inorganic compounds.
β οΈ Key Distinction Point: - If the mixture is primarily viewed as a chemical preparation/preparation not elsewhere specified (e.g., stabilized mixtures for specific HVAC use), it may fall under Chapter 38. - If it is viewed strictly by its chemical composition (halogenated hydrocarbons), it falls under Chapter 29 or 28. - The tax burden varies significantly (from 13.7% to 41.5%) based on the specific chemical classification chosen.

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
